select give an Error

Hi,

If I select or deselect in the list a row I get following error.

SCRIPT5007: Unable to get property 'node' of undefined or null reference

Here are my code, but did not see any faults. May you have a hint for me where my failure
is?

    Hi @Andreas S. ,

    That's a lot of code there. We're happy to take a look, but it would help, as per the forum rules, if you could link to a running test case showing the issue so we can offer some help. Information on how to create a test case (if you aren't able to link to the page you are working on) is available here.

    Cheers,

    Colin

    You have:

    mt_ls.button( 5 ).enable( selectedRows === 1 );

    But there is no button 5, so Buttons is correctly throwing an error. There are 5 buttons and it is zero indexed.
